I got it around chapter 8 or 9, unlocks a Sazh theme on the PS3 version lulz.

First room in the ARK, really easy trophy, xbox scrubs you fail:P hehe

I have to ask for those that have it on the 360 version, does anything like a theme or gamer pic unlock when you get that achievement on there? Man if there was a Sazh gamerpic I would totally go work on that achievement right now...

I dunno, I got it in the ARK as well, and I'm playing it on the PS3 so I couldn't tell you.  I was mostly wondering if everyone was using Libra as much as I was.

I pop Libra twice in the beginning of a fight on each new enemy...  Maybe I should stop.  I knew their stats filled in, but I want to have a full datalog by the end and I'm afraid I'll miss one I can't go back to.

Yep, there's a Sazh gamerpic that unlocks on 360.

I got it in the ark, great game but the ark part was kinda boring.

It's almost impossible to miss, probably the easiest gold in the game.  With Treasure Hunter probably being the most difficult   
 Many people make the mistake of thinking you have to libra every enemy multiple times, but just killing them 3-4 times will do, and it's almost impossible to not fight every monster 3-4 times.

Yeah this is so hard to miss unless you NEVER use Libra and you never fight the same enemy twice. I got a pretty cool gamerpic of Sazh which I will probably use once that contest ends and I can stop using that "XIII" gamerpic :P 
 
I got it on those Nudibranch enemies you fight in the Fifth Ark.

That's the most amazing thing I've ever heard, time to go play my 360 copy some more before actually finishing the damn game on PS3 (stupid school getting in the way). "
